Is handheld laser welding the future instead of TIG welding?

With the rapid development of industrial civilization, processing manufacturing industry has ushered in a huge change, the previous traditional processing technology has been unable to meet the needs of modern processing, with the rapid development of laser technology and widely used, has become one of the key technologies in the field of modern manufacturing. From the previous silk screen, knife engraving to today’s laser marking, engraving, from the previous punch, blade cutting to today’s laser cutting, from the traditional chemicals, acid cleaning to today’s laser cleaning, etc., the application of each laser technology will bring a major change to the traditional process, in line with environmental protection and green manufacturing based on the process more efficient, greater output, more beautiful process results, this is the laser to bring technological progress, the It is also an inevitable trend in the development of industrial technology.

In welding, too, there has been a change of process, from conventional electric welding and arc welding to laser welding. Laser welding of mainly metallic materials is currently the most important application. The development of laser welding in China has been nearly 30 years, but the small power YAG laser welding machine used in the past is often a stand-alone operation, the degree of automation is slightly lower, requiring manual loading and unloading, and the power is also low, the table width is small, it is difficult to operate large parts of the workpiece, resulting in the application of laser welding can not be spread. In recent years, laser welding has had greater development, especially the application of fiber laser welding, semiconductor laser welding, in the workpiece fixture, automatic control, automatic loading and unloading has also been good development, currently in the domestic part of the car factory has been equipped with high-end automated laser brazing body system, in addition to aviation parts, in the car body of the locomotive also has applications. There is also a very important is the new energy vehicles power battery laser welding. These are all embodiments of high-end applications of laser welding.

Handheld laser welding is spreading rapidly because it is convenient and easy to use. Compared to high-end automated laser welding applications, the requirements of various aspects, the technical threshold is very high, and handheld laser welding is exempt from fixtures, motion control considerations, back to the manual manual operation, the so-called workpiece alignment, alignment clamping are by hand. It cannot be said that this is a regression from automation to manual operation, but the actual application cost, acceptance to consider.

Take stainless steel welding, the current reality of the existence of a large number of welding processes, most of which are used in ordinary argon arc welding, spot welding, the development of so many years, is still a large number of manual operations, and the number of such welders are also many. In the stainless steel dosage of a large amount of kitchenware, kitchenware, bathroom hardware, stainless steel doors and windows, security fences, stainless steel furniture, hotel decoration and other industries are present in a large number of argon arc welding applications. This manual welding from the nature of welding is actually the traditional low-end welding process, generally welding thinner stainless steel sheet, stainless steel pipe. Today it is only the arc welding replaced by laser welding, in operation is very similar, the average welder less than half a day’s training to get started with handheld laser welding, so it is very high potential to replace the traditional argon arc welding.

Tigon-arc welding often requires a molten wire connection, resulting in a weld port that often has a protrusion, while laser welding does not require a wire and has a smoother interface. Argon arc welding is the development of many years, is the largest stock of welding processes, and laser welding is an emerging process, rapid development, but the total amount of welding is only a small part of the laser welding to replace part of the argon arc welding is an inevitable trend. Currently, from the use of cost considerations, argon arc welding is also very popular.

Argon arc welding often in order to save work and materials, only in the material selected corners of the fixed position to do spot welding, while laser welding is done along the seam zip type of welding, compared to the solidity of laser welding is much better. Currently handheld laser welding is commonly available in 500, 1000, 1500 and even 2000 watts, these power bands are sufficient for welding thin steel sheets. Nowadays, handheld laser welding equipment is becoming more and more compact, including the necessary chiller can be integrated into the whole chassis to achieve integration, mobile performance, procurement costs are much lower than before, can already meet the requirements of a large number of metal processing shops, processing plants, and even drag the equipment to the site work is no problem at all.
